// AGENT TYPE / AUTONOMOUS AGENTS

Your autonomous agents act with no one watching. Put hard limits on every call.

Always-on and scheduled agents run unattended through MCP, with no human to catch a bad call. Route them through PolicyLayer and every action is bounded by your policy before it runs.

BOUND YOUR AGENTS → Free to start. No card required.

For platform and security teams running AI agents in production.

// THE PROBLEM

An unattended agent has no one to stop it mid-call.

It rarely looks reckless. It looks like it's doing its job, faster than anyone can watch.

No human in the loop

A scheduled agent runs every hour with standing access to your systems and no approval moment.

A loop or a bad input compounds

One wrong instruction or a retry loop repeats an action hundreds of times before anyone notices.

It just keeps running

The blast radius is whatever the agent could reach, multiplied by how long it ran.

// THE SURFACE AREA

The standing access an autonomous agent holds.

An unattended agent keeps its tools between runs. PolicyLayer bounds every call.

// HOW POLICYLAYER WORKS

PolicyLayer sits between your autonomous agents and your systems.

Drop PolicyLayer into your MCP request path. Your agents keep their tools. You keep control. Core concepts →

⬢

MCP SERVER

Stripe, AWS, Postgres...

Add Stripe, GitHub, Postgres, Slack, AWS, or any other MCP server.

Define policy

Set defaults, rate limits, denials, approvals, hidden tools, and argument-level conditions.

Issue grants

Give each person, agent, CI job, or environment its own scoped token tied to a named policy.

Connect client

Paste the PolicyLayer proxy URL into your MCP client config. Agents keep the same tools. PolicyLayer enforces your rules before calls execute.

// ON EVERY CALL

What PolicyLayer enforces, on every call.

Hard rate caps

Cap actions per minute and per day, per token, so a loop cannot repeat a call into a real loss.

Tight per-token scopes

Each agent carries only the tools and resources its job needs, and nothing more.

Argument-level rules

Inspect the call: deny anything tagged production, block destructive statements, require a known job id. Writing policies →

Instant revocation

Pull an agent's grant the moment it misbehaves; the rest keep running.

Deterministic, deny by default

Rules run as code, first denial wins. The same call gets the same decision every time.

// POLICY EDITOR

You decide the hard limits on every autonomous call.

Build policy around the fields that matter (environment, resource tag, action class) in the visual editor. Allow, deny, rate-limit, or require approval, per tool. Writing policies →

PolicyLayer visual policy editor with allow, deny, hide and custom rules

Rate ceiling

No more than 5 destructive actions an hour, per token.

Approval on destructive

Deletes and payouts wait for a human, even unattended.

Scope to one job

Allow only the tools the agent's task needs.

Block production

Deny any action on resources tagged production by default.

Daily action cap

Total actions capped per day, per token.

// THE PLATFORM

Not just rules. A platform.

Whatever your agents touch, the same engine, audit, and access model is doing the work underneath every rule you write.

Deterministic engine

Rules run as code, not model judgement: argument-level conditions, quotas, deny-by-default. The same call gets the same decision every time.

Writing policies →

Separation of duties

Your security or compliance team writes and attaches policy without ever holding the upstream credentials or grant tokens.

Roles →

Tamper-proof audit

Every call is logged with its decision and the rule that fired, attributed to the identity, in an append-only record. Argument values are redacted, never stored.

Logs & security →

Credentials never reach the agent

Upstream secrets are encrypted at rest and injected by the gateway. The agent only ever holds a scoped token.

Logs & security →

Per-identity access

Every person and agent connects with its own scoped grant. Rotate or revoke any one of them instantly, without disrupting the rest.

Core concepts →

Live in minutes

Hosted gateway. Point your clients at it, register a server, issue a token. Nothing to install.

//FAQ

Autonomous agents and MCP questions.

There is no human to approve. How do controls work?+

For unattended agents you lean on deterministic limits and scopes rather than prompts: rate caps, narrow per-token scopes, and deny-by-default on destructive classes. Where you do want a human, an approval gate pauses that specific call and routes it for sign-off before a credential is issued.

Can I stop a misbehaving agent instantly?+

Yes. Each agent connects with its own scoped grant. Revoke it and that agent stops immediately, while every other agent keeps running.

Does PolicyLayer slow down automation calls?+

Policy is evaluated in memory before the call is forwarded, so the overhead is negligible. Allowed calls pass straight through to your systems.

Where do my service credentials live?+

Upstream credentials are encrypted at rest and injected by the gateway. Your agents only ever hold a scoped token, never your service credentials.

Do my agents lose any tools?+

No. Agents keep the same tools and schemas. PolicyLayer enforces policy on each call (allow, deny, rate-limit, or require approval), apart from any tools you deliberately hide.
